The uk economy is coming out of recession due to the cyclical nature of our economic system, not from any useful influence from any government party.
Government policies have simply slowed the process, so we now have an extremely weak recovery which will start heading south again in a few years as the next cyclical downturn kicks-in.
This recovery is so weak that most people don't feel it, and in many cases ;giving standards have only just recovered to pre crash levels.
If Labour are clever they can help lengthen the modest upswing and possibly increase vital spending as a result. Low oil prices and interest rate, coupled with zero inflation will help them. But its all short term and these 'good indicators' harm the economy in the longer term, and whatever is done, world economic conditions will dominate. Those aren't looking too good. Even the Chinese are now learning the hard lesson of the market, having embraced capitalism, experienced the boom and now see GDP heading rapidly south.
This is of course nothing new and these cycles have been with us for a few hundred years since the birth of this economic system. What's new is the severity of slumps and barely noticeable nature of the recoveries. This trend will continue until something snaps. The signs are already there on the continent.
Our electoral system is broken whichever method you choose because none will allow a challenge to the markets. You can have any flavour Starburst you like, but you
will have Starbursts
A movement for something on the real left would see the police on the streets, possibly the army, and the sort of state repression seen in Argentina.
